Specification of Letters Patent.

Application filed July 7, 1905. Serial No. 268,749.

To all whom it may concern:

Be it known that GEORGE W. GEsNER, deceased, late a citizen of the United States, did invent a certain new and useful Improvement in Articles of Alloy of Iron and Hydrogen and Processes of Producing the Same, of which the following is a specification. I

In United States Letters Patent No. 604,580, granted May 24, 1898; N 0. 642,320, granted January 30, 1900, and No. 670,775, granted March 26,1901, to the said GEORGE W. GEsNER are described and claimed certain processes of making alloys of iron and hydrogen, the product being in the form of a pig or ingot, powder, or scale. Accordin to these patents articles consisting of the a loy may be produced by remelting the pi s, powder, or scale and pourin the liquid al oy into molds, by forgin or ro ling heated masses of the alloy, or by eating the powder or scale and welding and shaping it by forging or roll- 1n The present invention relates to the production of articles consisting of particlesof the alloy of iron and hydrogen agglomerated into a strong coherent body. To produce such articles, the powdered alloy is preferably moistened and compressed into a body of the desired form. The body is then fired at a temperature sufficient to cause the component particles to frit or partially fuse together without melting down into a liquid mass. v

The invention will be more readily understood by reference to the accompanying drawings, in which Figure 1 is a transverse vertical section of a mold for compressing the powdered alloy into a rectangular plate. Fig. 2 is a perspective View of the compressed body or plate removed from the mold. Fig. 3 is a transverse vertical section of a number of the molded plates superposed and spaced apart by pieces of fire-brick in position to be fired, and Fig. 4 is a transverse vertical section of a series of molded plates inclosed in superposed spaced Inuflies for firing.

The mold shown in Fig. 1 comprises a steel body 1, having a recess 2 to receive the powdered alloy, and a plunger 3. To produce the initial body or late, the finely-pulverized alloy may be slig tly and uniformly dampened with water or other liquid and is then compressed in a mold, as by hydraulic ressure, until the particles cohere sufficient y to enable the resulting plate 4 to retain its form when removed from the mold. The plates are then heated to a temperature sufficient to cause the particles to frit or partially fuse together into a strong rigid body. Plates having a thickness of one-fourth of an inch are usually maintained at a temperature of about 2,000 Fahrenheit for about two hours. For the pu ose of firin the plates may be distribute within ,the urnace arranged in a pile or superposed with intermediate spacingpieces 5, of fire-brick, as shown in Fig. 3.

The molded lates may also be inclosed in sectional mu es or saggars 6, of refractory material, such as fire-brick, as shown in Fig. 4, the muflies being either distributed, piled one upon the other, or separated bys acers'5. After the plates have been properly filied the are preferably slowly cooled in ashes or pu verized charcoal or in an annealing-furnace, and their surfaces may finally be smoothed by grinding or otherwise.

To produce articles other than lates, suitable molds having cavities of t e required shape and properly subdivided may be employed, cores or mandrels being requisite when tubular articles are to be molded. The compression may be effected by the blow of a drop-hammer instead of a hydraulic press.

The alloy described in the specified patents is a materialof great value for many uses, such as the electrodes of electrochemical apparatus, chemical containers, and electrical conductors, resistors, and insulators. The present invention enables the material to be readily converted at little expense into strong and ri id articles of the desired form.

I claim as t e invention of the said GEORGE W. GEsNER 1. An article consisting of particles of an allo of iron and hydrogen, compressed and agg omerated into a strong coherent body, as set forth.

2. The process of producing articles of an alloy of iron and hydrogen, consisting in compressing the powdered alloy into a body, and

heating the body to a temperature sufficient IOC to cause the component particles to frit or partially fuse together, as set forth.

3.
